'WHIFFLETREE-CLIP.

S]? EGIFIGATION forming part of Letters Patent No. 734,798, dated July 28, 1903. Application filed May 12,1903- Serial No. 156,815. (llo model.)

To all whom it may concern:

Be it known that I, WALTER R. AYER,a citizen of the United States, residing at Planchette, in the parish of Pointe Coupee and State of Louisiana, have invented new and useful Improvements in Whiffletree-Glips, of which the following .is a specification.

This invention relatesto whiffletree-clips, and is in the nature of an improvement on the whiffietree-olip for which I obtained Let ters Patent on the 12th day of August, l902, No. 706,879, and has for its object toimprove and simplify the construction and render less expensive the manufacture of such clips and to render the clips lighter.

To these ends my invention consists in the features and in the construction, combination, and arrangement of parts hereinafter described, and particularly pointed out in the claims following the description, reference being had to the accompanying drawings, forming part of this specification, wherein Figure 1 is a perspective view of my improved clip. Fig. 2 is a View in side elevation, showing the Whiffletree in section. Fig. 3 is a sectional view taken on the line 3 3 of Fig. 2, and Fig. 4 isa plan view of the blank.

' rivet-holes 4:. A semicylindrical depression or socket is struck up by a die or in any other suitable manner centrally in each end of the blank, each of said sockets extending from the extreme end of the blank to the adjacent aperture 3. The blank is bent to form a substantially oval-shaped collar 1, and its two ends are caused to lie flatly one against the other and are firmly-and rigidly connected together by rivets 6, which pass through the rivet-holes 4 and are headed down at their opposite ends. When the ends of the blanks are thus brought together and secured to each other, the two semicylindrical depressions 5 register with each other and form a cylindrical socket 7. Y

The shank 8 of a hook 9 passes loosely through said socket and is threaded at its inner end. i The apertures 3 also register with each other, and fitted in said apertures is a nut 10, the sides of which are embraced by the side walls of said apertures, which prevent the nut from turning. The inner end of the shank '8 is threaded, as shown, and engages the nut 10, whereby when the hook is turned, the nut being held stationary, the shank of said hook is caused to move in or out of the socket,

The numeral 11 indicates a wear-plate, preferably lozenge-shaped, the ends of which. are pointed and bent downwardly at right angles to the body of said plate, as indicated at 12, to form penetrating prongs or teeth, andsaid wear-plate is provided centrally with a circular depression or step-bearing 13. In practice the hook is turned in a direction to retract or partially withdraw its shank. The

wear-plate isplaced at the desired point on the whiffletree, and the clip is then slipped over the end of the whiliietree and moved up into place over the wear-plate. Then by turning the hook in the proper direction its shank is caused to move inwardly and engage the step-bearing 13 of the socket-plate, and upon continuing to turn the hook in the same direction the prongs 12 of the wear-plate are firmly embedded in the whiflietree and the collar is drawn tightly in place around or about said whiflietree, thus firmly holding the clip in place. The hook 6 will be of any suitable shape to connect to a suitable fastening (not shown) on the doubletree or clevis, or instead of be-,

ing made in theform of a hook may be made in the form of an eye or loop. The clip may be adjusted from one point to another on the whifflotree should it be desirable so to do, it being only necessary to loosen the hook and slip the clip from off the wear-plate. Then by a suitable tool-such as a screw-driver, for example-the wearplate can be detached from the whiffletree and moved to such other point as may be desired and the clip then moved over the wear plate and the hook screwed up into engagement therewith.

I have hereinbefore stated that the collar is constructed, preferably, of sheet steel or iron. It will of course be apparent that it may be of any other suitable material, and

while I prefer for the sake of economy in manufacture to construct it of sheet steel or 7 iron I do not wish to be understood as confining myself to such material.

It will be noticed that the back of the band or clip is provided with a diamond-shaped opening, (indicated by 14:.) This opening will cause the outer edges of the clip to embrace the wood of the whiffletree, and thereby tend to insure a uniform and equal bearing in the event that the wood should be a little larger in the center of the band and tapering to the ends.

Having described my invention, what I claim isp 1. A clip for whifiietrees comprisinga collar provided at one side with a sleeve or socket, a hook having a threaded shank movably fitted in the sleeve or socket, and a nut disposed at the inner end of the sleeve or socket and. held against rotation, a threaded end of the shank engaging said nut, substantially as described.

2. A clip for whiffletrees comprising a collar provided at one side with a sleeve or socket, and provided with a rectangular aperture at the inner end of the socket, a nut fitted in said aperture and held therein against rotation, and a hook provided with a threaded shank movably fitted in said socket and engaging said nut, substantially as described.

4. A clip for whifliletrees comprising acollar provided at one side with a sleeve or socket, a hook having a threaded shank movably fitted in the sleeve or socket, a nut disposed at the inner end of the sleeve or socket and held against rotation, a threaded end of the shank engaging said nut, and a Wear-plate having prongs adapted to penetrate the Whitfletree and provided. centrally with a step-bearing,.

the inner end of the shank of the hook being arranged to engage said step-bearing,substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
